Exporting modified values to csv format

I performed some color manipulations on a few Sentinel bands.
When I tried exporting them as CSV files. The values are not the modified values (after the colour manipulations) but the original pixel values.

How can I export the modified pixel value? Kindly suggest.

The geophysical values always stay the same in SNAP, except the data is processed to some higher level.
The colour manipulation changes only how the data is visually displayed but the values stay the same. As the values represent usually measurements you can’t change the measurement afterwards.

If you want to changes the values you need to process the data by one of the available processors or the Band Maths.
